MD4 Hash Ikhodi Calculator

I-MD4 (i-Message Digest 4) umsebenzi we-hash we-cryptographic owaklanywa nguRonald Rivest ngo-1990. Ikhiqiza inani le-hash elingaguquki elingu-128-bit (16-byte) kusuka kokufakwayo kobude obungahleliwe. I-MD4 manje ibhekwa njengephukile ngokwe-cryptographic ngenxa yobuthakathaka obuvumela ukuhlaselwa kokushayisana (ukuthola okufakwayo okubili okuhlukile okukhiqiza i-hash efanayo), ngakho-ke akufanele isetshenziswe lapho kuklanywa izinhlelo ezintsha. Ifakiwe lapha uma kwenzeka umuntu edinga ukukhiqiza ikhodi ye-hash ehambisanayo emuva.

Ukudalulwa okuphelele: Angibhalanga ukusetshenziswa okuqondile komsebenzi we-hashi osetshenziswe kuleli khasi. Kungumsebenzi ojwayelekile ofakwe nolimi lokuhlela lwe-PHP. Ngenze isixhumi esibonakalayo sewebhu kuphela ukuze ngisenze sitholakale esidlangalaleni lapha ukuze kube lula.

Mayelana ne-MD4 Hash Algorithm

Angisiye isazi sezibalo, ngakho-ke ngizozama ukuchaza lo msebenzi we-hash ngendlela abanye ochwepheshe bezibalo abangayiqonda ;-) Uma ukhetha incazelo enzima yezibalo, ungayithola kwamanye amawebhusayithi amaningi.

Kulungile, ngakho cabanga nge-MD4 njengomshini wokusika amaphepha okhethekile. Kodwa esikhundleni sokusika amaphepha, "usika" noma yimuphi umlayezo (njengohlamvu, iphasiwedi, noma incwadi) ube irisidi elincane, elingaguquki. Kungakhathaliseki ukuthi umlayezo wakho mkhulu noma mncane kangakanani, lo mshini wokusika amaphepha uhlala ekunika irisidi elincane elingama-byte angu-16 (ama-bits angu-128) ubude, noma izinhlamvu ezingu-32 ngesimo se-hexadecimal.

Ukuze umlayezo uhlukaniswe kahle, udinga ukuthatha izinyathelo ezine:

Isinyathelo 1: Ukulungiselela Umlayezo

• Ngaphambi kokusikwa, kufanele ulungise iphepha lakho ukuze lilingane kahle ne-shredder.
• Uma umlayezo wakho umfushane kakhulu, ungeza isikhala esingenalutho esengeziwe (njengama-doodle noma ama-filler) ukuze iphepha lilingane kahle.
• Uma inde kakhulu, uyihlukanisa ibe amakhasi amaningi anobukhulu obufanayo.

Isinyathelo 2: Ukwengeza Isitembu Esiyimfihlo

• Ngemva kokulungisa umlayezo, ufaka isitembu esiyimfihlo ekugcineni esibonisa ukuthi umlayezo wokuqala ubude kangakanani.
• Lokhu kusiza umshini wokusika umlayezo ukuthi ulandelele usayizi wokuqala womlayezo, kungakhathaliseki ukuthi ungeze okungakanani ukugcwalisa.

Isinyathelo 3: Inqubo Yokunquma (Imijikelezo Emithathu Yomlingo)

• Manje umyalezo ungena kumshini wokugunda izinwele.
• I-shredder inamagiya amane (A, B, C, kanye no-D) ajikeleza ndawonye ngendlela ekhethekile.
• Amagiya adlula emizuliswaneni emithathu yokuzungeza, lapho: Hlanganisa khona amagama Phendula ezinye izingxenye phansi Zijikise njengekhiyubhu kaRubik Hlakaza izingcezu ezahlukene ndawonye
• Umjikelezo ngamunye wenza umlayezo ubukeke njengokudideka okungaqondakali.

Isinyathelo 4: Irisidi Lokugcina

• Ngemva kwakho konke ukusonta, ukupheqa, nokuphula, umshini wokuhlikihla ukhipha irisidi - uchungechunge olufushane lwezinombolo nezinhlamvu (i-hash).
• Leli risidi lihlala linobude obufanayo, kungakhathaliseki ukuthi uhlukanise igama elilodwa noma incwadi yonke!

Ngeshwa, ngokuhamba kwesikhathi, abantu bathola ukuthi lo mshini wokugaya imfucuza omangalisayo awuphelele. Abanye abantu abahlakaniphile bathola indlela yokukhohlisa umshini wokugaya imfucuza ukuthi unikeze irisidi elifanayo lemiyalezo emibili ehlukene (lokhu kubizwa ngokuthi ukushayisana) nokubikezela ukuthi amagiya azojikeleza kanjani bese bewasebenzisa ukudala amarisidi mbumbulu. Ngenxa yalokhu, i-MD4 ayisabhekwa njengephephile ezintweni ezibalulekile.
